Toyota - Corolla :: 2004 - Check Engine Light On / Oxygen Sensor Faulty
Jan 20, 2012
I have a 2004 Corolla with a Check Engine light on. The Toyota dealer diagnosed this as: "Oxygen Sensor Bank 1 Sensor 1 - slow to respond".
The diagnostic code is PO133. Elsewhere, I find that this code indicates:
The oxygen sensor is faulty.
The wiring to the sensor is broken / frayed.
There is an exhaust leak
Haven't noticed exhaust leakage, and I doubt the wiring is faulty.
1) Where is sensor 1?
2) Do I really need a new sensor, or can I clean the old one?

I own a 2000 Toyota Camry that was given to me by my father. The check engine light illuminated last year so I brought the car in to my mechanic. He said it was the o2 sensor and changed it. That lasted about a month , and the light went on again. This time it had to do with some valves that get stuck open (or closed) but also had to do with the amount of oxygen that goes into the carburetor . I asked my Dad if he had this problem, and he told me that the engine light was illuminated often, that he had brought the car in about 6 times, but nothing was found. Previously I owned a 1998 Camry, and had the same problem; the check engine light illuminates, the diagnosis is the oxygen sensor, that gets changed, the light goes on again, this valve thing gets changed but the light goes on again in a month. I can't get the car inspected with the engine light illuminated. The light always goes back on but nothing else is found wrong with the vehicle. I really know nothing about cars.

Engine runs perfectly but "check engine" light" stays on due to faulty Emission Evap control pressure sensor (P/N; 89460-0w020). Problem is Toyota no longer makes this part and there is no after market for it. It appears I may have to "junk" a perfectly good truck.

We took our 2008 Prius in for a check engine light. The dealership said oxygen sensor was faulty. Changed that and had them change the serpentine belt while there due to cracks in the belt. My wife filled up the car the next day ( it took 13 gallons) but gas gauge was not registering a full tank. We drove 67 miles and I decided to pull into a gas station and see how much it would take since the gas gauge was not working properly. It took over 7 gallons.

I recently bought my new (For me) R32, the first owner of the car remove the 2 catalyst from the car and now I have the check engine light on. When my friend put the vagcom on the car it shows an oxygen sensor fault. What can I do to fix this? can I just buy a MagnaFlow exhaust?

The "check engine soon" light appeared yesterday on this nice running 1997 van with 167K. An auto parts store code check indicated a problem with the oxygen sensor. Is this something I can replace myself--a lightweight shade tree mechanic? I never seem to have any luck asking questions on the Mopar website.

I have a hyndai Sonata v6. It is 2006 model and has done 86K miles. It recently failed the inspection and I was told it has faulty oxygen sensors. I have replaced the sensors. But now I am advised by the mechanic that I need to drive abut 200 miles before I can take it for the inspection again because it takes some time for the sensors to get adjusted. Is that true ?

I thought this strange occurrence I am about to describe was maybe happening because of a faulty air-fuel oxygen sensor, that I knew was bad do to a code test that was done, when my check engine light came on. However, after changing the air-fuel oxygen sensor, doing a reset on my check engine light over the weekend, this same occurrence is happening, to spite the check engine light remaining off. Here is what is happening.
When I start and drive it to normal driving temperature then put the car in "Park" with nothing turned on, the car will shake the idle speed will move up and down until it will eventually kill.
Special Note: It does not always have a idle drop and kill the engine every time. If I turn the A/C on in "Park" it idles up higher and does not ever kill. Could it be a bad Idle Air Control Motor?

I have a 2004 Toyota Corolla.
Check engine light was on so I took the car to Midas they pulled a code (133) and they said its Oxygen Sensor is not working. I took the car to Auto Zone for second opinion, Auto zone confirmed that Oxygen Sensor might be having problem. Then I inquire in couple of places for the price to fix O2 sensor, all most all places I got the same quote to fix it.And after a day or so check engine light went off. Check engine light was on for a day or so.
Now I am confused, is there a problem with Oxygen sensors? Should I still go ahead and fix these sensor or should I wait till Check engine light comes back again?

I was wondering if this seems reasonable. I just bought a used 2008 Prius top trim package with 107,00 miles on it this last month. The first day I owned it a check engine light was triggered. The guy I bought it from hooked it up to his computer and cleared it to then try to trigger it again. This happened when I first turned on the car. I started backing and then it turned on. I didn't know what caused it as we couldn't trigger the response again. It's been a few weeks now and 1 trip to the shop for some repairs. There have been no problems what-so-ever since then and my Prius just started getting close to the 50 MPH as advertised after a tune up.
Today when I'm driving, as the seller did mention before could happen, the right headlight turned off. As he had told me before, just turning the lights off and turning them back on will get it working again. I did this and as soon as I did the check engine light came on. I go back to the night I originally had it happen and I was probably in the process of turning on my lights.

I have a 2010 Toyota Corolla 1.8L, the base model.
I recently had a check engine light, VSC off light (blinking) and traction control light come on. I took it to Autozone and had a p0037 code ring up for a new Bank 1 Sensor 2 oxygen sensor (downstream). I believe I have found the correct sensor (located under car, approximately near drivers seat) and it looks simple to replace, aside from the fact that the wires go through the car body.
Can confirm that I have located the correct sensor? And if so, what is the best way to get to where the wires connect?
Is it located under the drivers seat? What should I do about the rubber grommet located under the car where the wires appear to pass through?

1989 toyota 4runner. O2 sensor is bad and has the check engine light on. No need to spend $100+ on the sensor. Is there a way to disable it so the light goes off?

This is a California car that won't pass smog tests with a lit check engine light. I don't know the specific code, but the description is that the torque converter is staying in the "off" position. Apparently the lock up torque converter is part of the emissions system in that if the torque converter does not lock up then the rpm's are higher and that produces more pollutants.
1st step was to flush out the transmission and the flush made sure all the fluid in the torque converter was removed and replaced. After that was done the trans fluid has stayed nice and clean and pink for about 400 miles. The CEL was turned off after this service but came back on in a few days at about 200 miles. Next, the solenoid that activates the torque converter was replaced. The CEL was turned off again, an this time the CEL came back on after a hour of driving on local errands.
Me and my generally good mechanic are hung up now. We were betting the solenoid change out would solve the problem. It seems that the torque converter is in fact operating properly. The tranny shifts smoothly and the rpm's drop at the proper times indicating the torque converter is locking up.

At a service station in NJ, my gas cap flew into the wind and the attendant replaced it. My check engine light came on a day after getting gas (not in NJ) so I took it in to my garage. Ends up that the (new) gas cap has a crack and a new one is getting ordered. Now, whenever I am filling up the gas tank, it keeps shutting itself off (very frequently . . . like every 1/2 gallon or so). This happened when the check engine light was on and after it was initially turned off by the mechanic. I asked a mechanic at the garage because it keeps happening and I can't fill the car fully and he said it happens with some cars and you have to hold it a certain way or something. This can't be fixed and I'll just have to get used to it until I get a new car. My question -- how could this have just started happening? Its a 2002 Corolla and I've had it for years without problems. Is it possible that when I get a new gas cap and the computer gets re-started, it will fix itself?

I have a Toyota Corolla 96. The check light is on. I took it to AutoZone and the guy told me everything is Ok. I looked the oil level this morning and it was low. The temperature sensor is normal and the car runs fine. My car experience is almost zero....

My girlfriend's 2001 Toyota Corolla has a recurrent Check Engine light problem. It has 144,000 miles on it. For the last few years, we have been unable to keep the light turned off. We have replaced the oxygen sensors and cleaned the MAF sensor. Our mechanic can't find the problem.

For a few months, I have been getting check engine lights on my Toyota Corolla 2002. The check engine light often goes away by itself.
I took my car to a mechanic with a decent reputation after a couple weeks of the problem. He thought he fixed it and gave the car back to me. The check engine light kept coming back on, and I kept going back. The mechanic topped off the coolant, replaced certain hoses, host clamps, sensors and other parts (like the solenoid canister). After the fifth trip back (and eight weeks of time), he refunded my money.
The check engine light comes on and goes off. Right now with no check engine light on, I get codes P0125 and PO441 PD.
What will happen if I keep ignoring these check engine lights or the codes that persist when the check engine light is not on? I was thinking of going to another mechanic. I think I want to wait for a few more weeks to see if I notice a pattern. I do not drive that many miles each day (much less than average).

I have a 2002 Toyota Corolla CE with about 115,000 miles.While I was traveling on the highway my car started shaking, losing power, and the check engine light started flashing. I drove a mile or two to a rest area because I didn't want to pull over on the highway. I had it towed home. It starts and idles, but I'm afraid to get it out on the road.

Had the oil changed today; before doing so, I saw that the check engine light had come on. Have been told by 3 professional car maintenance people that there is no connection between needing oil / oil change and check engine, that it would have been the check maintenance light.
Will take it in for diagnostic test by dealer. Also, was told by the oil change guy that he heard pinging which could mean that the car needs to have the valves adjusted, and that the check engine light is due to needing something or other with the gas tank filter which could have a leak/crack, etc.

The check-engine light on my 2006 Toyota Corolla came on a couple of weeks ago after I started the car on a 7-degree F morning. Code was P-0171. Mechanic cleaned the MAF and the light went off. Light stayed off 'til I started the car on another 7-degree F morning. Mechanic said that the MAF didn't look dirty, and the readings didn't change after cleaning. No vacuum leaks. O2 sensors responding normally. What's going on? I travel a lot in this car, so I don't want to damage the car by ignoring the check-engine light.
